to the daughter or the sister.
Likewise, a son’s son renders as residuary heirs the female descendants at his own degree, as well as those above him, provided they have not received any of the two-thirds. Thus, if a person dies leaving two daughters and a son’s daughter, the two daughters receive two-thirds, and the son’s daughter receives nothing. But if there is a son’s son at her degree, or a son’s son’s son below her, the remainder is divided between them, with the male receiving the share of two females.
A full sister or paternal half-sister becomes a residuary heir alongside a daughter. Thus, if a person dies leaving a daughter and a sister, the daughter receives one-half and the sister receives the remainder. If he dies leaving two daughters and a sister, the two daughters receive two-thirds and the sister receives the remainder.
The evidence for this is what ‘Abd al-Wāḥid al-Mulayḥī informed us: Aḥmad ibn ‘Abd Allāh al-Nu‘aymī informed us; Muḥammad ibn Yūsuf informed us; Muḥammad ibn Ismā‘īl informed us; Ādam informed us; Shu‘bah informed us; Abū Qays informed us, who said: I heard Hudhayl ibn Shuraḥbīl say: Abū Mūsā was asked about a daughter, a son’s daughter, and a sister. He replied, “The daughter receives one-half, and the sister receives one-half. Go to Ibn Mas‘ūd, and he will agree with me.” Ibn Mas‘ūd was then asked and informed of Abū Mūsā’s ruling. He said, “If I were to rule thus, I would have gone astray and would not be among those rightly guided. I rule concerning her as the Messenger of Allah, peace and blessings be upon him, ruled: the daughter receives one-half; the son’s daughter receives one-sixth, completing two-thirds; and what remains belongs to the sister.” We then went to Abū Mūsā and informed him of Ibn Mas‘ūd’s ruling, may Allah be pleased with him. He said, “Do not ask me while this learned scholar is among you.” (1)
We return to the explanation of the verse. They differed concerning the reason for its revelation. ‘Abd al-Wāḥid al-Mulayḥī informed us: Aḥmad ibn ‘Abd Allāh al-Nu‘aymī informed us; Muḥammad ibn Yūsuf informed us; Muḥammad ibn Ismā‘īl informed us; Abū al-Walīd informed us; Shu‘bah informed us from Muḥammad ibn al-Munkadir, who said: I heard Jābir say: The Messenger of Allah, peace and blessings be upon him, came to visit me while I was ill and unconscious. He performed ablution and poured some of the water from his ablution over me, whereupon I regained consciousness. I said, “Messenger of Allah, who will inherit me? My heirs are only collateral relatives.” Then the verse of the prescribed shares was revealed. (2)
Muqātil and al-Kalbī said: It was revealed concerning Umm Kujjah, the wife of Aws ibn Thābit, and her daughters. (3)
‘Aṭā’ said: Sa‘d ibn al-Rabī‘, the tribal leader, was martyred on the day of Uḥud, leaving behind a wife, two daughters, and a brother. The brother took the estate. Sa‘d’s wife then came to the Messenger of Allah, peace and blessings be upon him, accompanied by Sa‘d’s two daughters, and said: “Messenger of Allah, these two are Sa‘d’s daughters, and Sa‘d (4) was killed as a martyr on the day of Uḥud. Their uncle has taken their property, and they cannot be married unless they possess wealth.” The Messenger of Allah, peace and blessings be upon him, said, “Go back, for perhaps Allah will issue a ruling concerning this matter.” Then the words, “Allah instructs you,” were revealed until the end of the verse. The Messenger of Allah, peace and blessings be upon him, then summoned their uncle and said to him, “Give Sa‘d’s two daughters two-thirds, their mother one-eighth, and whatever remains is yours.” (5) This was the first inheritance to be distributed in Islam.
